چکیده [English]

AbstractThe use of satellite imagery can be a very useful tool to describe the interrelationships between the human environment and the natural environment to help planners make decisions in complex situations. The process of urban development of cities is one of the basic needs in management and evaluation. In addition, amount of growth of cities, the study of changes amount and land use destruction in past years, and predict these changes in the coming years can help in the correct management and planning to solve the current problems and future development planning program. In this regard, this study tends to using Satellite imagery Landsat Tm in 1988 and Satellite imagery of LandSat ETM in 20011 to assess the physical growth and in order to expansion of Ardabil. This study is consistent with periods before and after political centrality of Ardabil. For this order after the satellite image processing, the images were classified using maximum likelihood method and finally in geographic information system (GIS) by applying changes function were obtain land use changes. According to the conducted investigations it was concluded that physical growth of Ardabil after the political centrality has taken great acceleration, and during the physical growth of the city, agricultural land around the city has gone under construction in the city.
